New energy and ringEnvironmental protection: The demand for new energy technology and environmental protection for chip technology is also increasing. For example, chips for solar and wind energy conversion, as well as chips for environmental monitoring and control. The development of chip technology will support more efficient and sustainable energy use, as well as more refined and precise environmental protection. Biotechnology and Healthcare: Chip technology is also widely used in biotechnology and healthcare.
The high-quality development of the chip industry is directly related to the progress of the modern information industry and industrial chain. During the 13th Five-Year Plan period, China's integrated circuit industry developed rapidly, and the industrial scale continued to grow. Per rowIndustry estimates that in 2020, China's integrated circuit sales revenue reached 884.8 billion yuan, with an average growth rate of 20%, far exceeding the global industry growth rate.The employment prospects of chips are as follows: Market demand: With the continuous progress of science and technology and the expansion of applications, integrated circuit technology has a wide and deep application in various fields, such as electronic communications, computers, medical equipment, consumer electronics, automotive and other industries. Therefore, the demand for integrated circuit technical personnel continues to grow, the contradiction between market supply and demand is small, and the employment prospects are good.
Chip professional employment prospects are better, the industry demand is growing. lineTo manufacturers of terminal equipment, such as set-top box manufacturers.
LM386 is a high gain, low voltage linear amplifier chip, its internal circuit includes multiple transistors, but this does not mean that its magnification is only a few times. The magnification of the LM386 is adjusted by configuring a triode on the internal circuit, which can usually be selected between 10x and 1000x. This chip is designed to achieve low voltage drive and high gain output, and its main principle is to use the current amplification of the transistor.
Most of the connections inside are copper wire connections, of course, some are pureGold or sterling silver. The functions they achieve depend on the design of the circuit, as you can understand, just like the CPU of the computer, there are billions of electronic components, nothing more than those resistors, capacitors, diodes, audiodes, field effect tubes, etc., but the larger the number, the more complex the function or the circuit logic to achieve.
Their application circuit is the same. Above is a single power OTL power amplifier circuit composed of the power amplifier integrated module. TDA2030A and TDA2030 are power amplifier IC circuits used to assemble integrated circuit audio. Believe a lot of electricityAll the enthusiasts have tried it. For example, if the circuit is designed well, add a nice tone circuit, and then design it into a two-channel binary frequency or three-frequency circuit, you can obtain better sound quality.
Chips are so important in our lives, then how much do we know about the chip? In fact, the chip is an integrated circuit, which is an electronic product obtained by microprocessing technology, which gathers semiconductor devices on the surface of silicon wafers. It is this small electronic device that determines the quality of our lives today.
The so-called chip is the carrier of the integrated circuit. To put it simply, put a lot ofDiodes, transistors, and circuits can be reduced to a small silicon chip, which can realize a complete set of circuit functions and greatly reduce the volume. At the same volume, the circuit performance can be greatly increased. Therefore, the vast majority of modern electrical appliances and digital products have chips. Such as USB flash drives, cameras, TV sets, and so on.
1, China has accelerated the localization of chips, the development of chips in the future should be moreA kind of technology parallel, now the manufacture of high-precision chips is mainly through the lithography machine, obviously the future lithography machine is also a very, very important part, but there should be other technologies do not simply look to this lithography machine, because the road after two nanometers in the end how to go, is now controversial.
2. Here are some possible opportunities: Domestic substitution is unstoppable. From the closure and upgrading of the United States' science and technology policy toward China, from the plight of ZTE to the supply of Huawei chips, semiconductors bear the responsibility of protecting the strategic security of domestic industries, and the trend of "domestic substitution" of supply chain localization is unstoppable. AI chips have become the focus of development. Since theSince the importance of artificial intelligence was first mentioned in the government work report in 2017, AI has gradually become the focus of development in China.
3, China's chip industry has great prospects for development. On June 9, 2021, at the World Semiconductor Conference, Wu Hanming, academician of the Chinese Academy of Engineering, pointed out the status quo of China's chips: China wants to complete the localization of chips and replace them, and there is still a shortage of 8 core international. In short, today China needs the capacity of eight SMIC companies to meet the growing demand for chips in the current semiconductor market.
4, semiconductor manufacturing equipment is subdivided in some domestic wafersIn the procurement of the factory, the localization rate of rubber removal equipment is close to 90%, which is the highest localization rate in semiconductor manufacturing equipment. China's semiconductor industry is experiencing industry recovery and domestic substitution opportunities brought about by an explosion in downstream demand. Amorphous semiconductor is not a physical processing, but a chemical means to directly change the position of the atoms, so that the original periodic change, the formation of amorphous silicon.
5, China's artificial intelligence chip industry will develop rapidly, and the market size is expected to exceed 100 billion yuan in 2023. To sum up, China's artificial intelligence chip industry is still in its infancy, no matter from the number of enterprisesFrom the perspective of core technology, the layout is still shallow, but as the foundation of the artificial intelligence industry, with the further development of 5G technology and the popularity of applications in China in the future, the artificial intelligence chip industry is expected to ride the trend.
6, indicating the stage results of China's etching machine in improving localization and global competition. Outlook: The nation's power to develop chip technology, not subject to others. In June 2000, The State Council issued the "Several Policies to Encourage the development of the software Industry and integrated circuit Industry", which is the use of capital, talent introduction, tax incentives and other ways to develop the IC industry.
2, IBM leads the forefront of technology,Global technology giant IBM recently released a landmark innovation product - the world's smallest 2-nanometer chip, a revolutionary semiconductor technology that combines improved performance with reduced energy consumption. Compared to the mainstream 7-nanometer chips on the market, this chip improves performance by a staggering 45%, while reducing energy consumption to an incredible 75%.
3, slogan: Nano technology, leading the future, micro miracle, within reach! The promise and fascination of nanotechnology, one that leads us into microscopic wonderCutting-edge technology in the world. It is not only a branch of science, but also the key to the future innovation of technological products and the improvement of quality of life. The nanometer, a small unit of length, holds enormous power to change the world.
4, nanochip is a chip technology, the key feature is that the component or line size on the chip reaches the nanometer level, usually in the nanometer meter scale (nanometer level is a billionth of a meter) range. This size is much smaller than the component sizes found on traditional microelectronic chips, and therefore has some unique performance and application advantages. Here are some key points about nanochips: SizeThe key feature of nanochips is their nanoscale size.
